prove tan^2(x)(1+cos(2x))=sin^2(x)

prove

tan^{2} (x) (1 + cos (2 x)) = sin^{2} (x)

False

Solution steps

tan^{2} (x) (1 + cos (2 x)) = sin^{2} (x)

Show that the two sides are not equal

\Rightarrow False

\frac{tan ( x )}{csc ( x )} = \frac{1}{cos ( x )} - \frac{1}{sec ( x )}

\frac{sin ^{2} ( 2 x )}{1 - cos ( 2 x )} = 2 cos^{2} (x)

tan (θ) sec^{2} (θ) tan (θ) = tan^{3} (θ)

1 - 2 sin^{2} (\frac{x}{4}) = cos (\frac{x}{2})

cos^{2} (b) + sin^{2} (b) = 1
